getReturnConsumedCapacity

public String getReturnConsumedCapacity()

withReturnConsumedCapacity

public GetItemSpec withReturnConsumedCapacity(ReturnConsumedCapacity capacity)

getAttributesToGet

public List<String> getAttributesToGet()

withAttributesToGet

public GetItemSpec withAttributesToGet(String... attrNames)

isConsistentRead

public Boolean isConsistentRead()

withConsistentRead

public GetItemSpec withConsistentRead(boolean consistentRead)

getProjectionExpression

public String getProjectionExpression()

withProjectionExpression

public GetItemSpec withProjectionExpression(String projectionExpression)

When a projection expression is specified, the corresponding name-map can optionally be specified via { withNameMap(Map). (Note attributes-to-get must not be specified if a projection expression has been specified.)

getNameMap

public Map<String,String> getNameMap()
