Block (AWS SDK for Java

java.lang.Object
- software.amazon.awssdk.services.textract.model.Block

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<Block.Builder,Block>
```
@Generated(value="software.amazon.awssdk:codegen")
public final class Block
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Block.Builder,Block>
```
A Block represents items that are recognized in a document within a group of pixels close to each other. The information returned in a Block object depends on the type of operation. In text detection for documents (for example DetectDocumentText), you get information about the detected words and lines of text. In text analysis (for example AnalyzeDocument), you can also get information about the fields, tables, and selection elements that are detected in the document.

An array of Block objects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText, the array of Block objects is the entire set of results. In asynchronous operations, such as GetDocumentAnalysis, the array is returned over one or more responses.

    - PAGE - Contains a list of child Block objects that are detected on a document page.
    - KEY_VALUE_SET - Stores the KEY and VALUE Block objects for linked text that's detected on a document page. Use the EntityType field to determine if a KEY_VALUE_SET object is a KEY Block object or a VALUE Block object.

    Returns:
    
    The row in which a table cell is located. The first row position is 1. RowIndex isn't returned by DetectDocumentText and GetDocumentTextDetection.

  - id
```
public final String id()
```
    The identifier for the recognized text. The identifier is only unique for a single operation.
    
    Returns:
    
    The identifier for the recognized text. The identifier is only unique for a single operation.
  - hasRelationships
```
public final boolean hasRelationships()
```
    For responses, this returns true if the service returned a value for the Relationships property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - relationships
```
public final List<Relationship> relationships()
```
    A list of child blocks of the current block. For example, a LINE object has child blocks for each WORD block that's part of the line of text. There aren't Relationship objects in the list for relationships that don't exist, such as when the current block has no child blocks. The list size can be the following:
    - 0 - The block has no child blocks.
    - 1 - The block has child blocks.
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasRelationships() method.
    Returns:
    A list of child blocks of the current block. For example, a LINE object has child blocks for each WORD block that's part of the line of text. There aren't Relationship objects in the list for relationships that don't exist, such as when the current block has no child blocks. The list size can be the following:
    
    0 - The block has no child blocks.
    
    1 - The block has child blocks.
  - entityTypes
```
public final List<EntityType> entityTypes()
```
    The type of entity. The following can be returned:
    - KEY - An identifier for a field on the document.
    - VALUE - The field text.
    EntityTypes isn't returned by DetectDocumentText and GetDocumentTextDetection.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEntityTypes() method.
    Returns:
    The type of entity. The following can be returned:
    
    KEY - An identifier for a field on the document.
    
    VALUE - The field text.
    
    EntityTypes isn't returned by DetectDocumentText and GetDocumentTextDetection.
  - hasEntityTypes
```
public final boolean hasEntityTypes()

This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map.

  - entityTypesAsStrings
```
public final List<String> entityTypesAsStrings()
```
    The type of entity. The following can be returned:
    - KEY - An identifier for a field on the document.
    - VALUE - The field text.
    EntityTypes isn't returned by DetectDocumentText and GetDocumentTextDetection.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEntityTypes() method.
    Returns:
    The type of entity. The following can be returned:
    
    KEY - An identifier for a field on the document.
    
    VALUE - The field text.
    
    EntityTypes isn't returned by DetectDocumentText and GetDocumentTextDetection.
  - selectionStatus
```
public final SelectionStatus selectionStatus()
```
    The selection status of a selection element, such as an option button or check box.
    
    If the service returns an enum value that is not available in the current SDK version, selectionStatus will return SelectionStatus.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from selectionStatusAsString().
    
    Returns:
    
    The selection status of a selection element, such as an option button or check box.
    
    See Also:
    
    SelectionStatus
  - selectionStatusAsString
```
public final String selectionStatusAsString()
```
    The selection status of a selection element, such as an option button or check box.
    
    If the service returns an enum value that is not available in the current SDK version, selectionStatus will return SelectionStatus.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from selectionStatusAsString().
    
    Returns:
    
    The selection status of a selection element, such as an option button or check box.
    
    See Also:
    
    SelectionStatus
  - page
```
public final Integer page()
```
    The page on which a block was detected. Page is returned by asynchronous operations. Page values greater than 1 are only returned for multipage documents that are in PDF format. A scanned image (JPEG/PNG), even if it contains multiple document pages, is considered to be a single-page document. The value of Page is always 1. Synchronous operations don't return Page because every input document is considered to be a single-page document.

    obj - the object to be compared with
