Method Detail

builder

public static ScanEnhancedRequest.Builder builder()

Creates a newly initialized builder for a request object.

toBuilder

public ScanEnhancedRequest.Builder toBuilder()

Returns a builder initialized with all existing values on the request object.

exclusiveStartKey

public Map<String,AttributeValue> exclusiveStartKey()

Returns the value of the exclusive start key set on this request object, or null if it doesn't exist.

limit

public Integer limit()

Returns the value of limit set on this request object, or null if it doesn't exist.

segment

public Integer segment()

Returns the value of segment set on this request object, or null if it doesn't exist.

totalSegments

public Integer totalSegments()

Returns the value of totalSegments set on this request object, or null if it doesn't exist.

consistentRead

public Boolean consistentRead()

Returns the value of consistent read, or false if it has not been set.

filterExpression

public Expression filterExpression()

Returns the return result filter Expression set on this request object, or null if it doesn't exist.

attributesToProject

public List<String> attributesToProject()

Returns the list of projected attributes on this request object, or an null if no projection is specified. Nested attributes are represented using the '.' separator. Example : foo.bar is represented as "foo.bar" which is indistinguishable from a non-nested attribute with the name "foo.bar". Use nestedAttributesToProject() if you have a use-case that requires discrimination between these two cases.

nestedAttributesToProject

public List<NestedAttributeName> nestedAttributesToProject()

Returns the list of projected attribute names, in the form of NestedAttributeName objects, for this request object, or null if no projection is specified. Refer NestedAttributeName

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
