Method Detail

clone

public ExprNode clone()

Makes a full clone in new memory space of the current node and children

Specified by:

clone in interface ExprNode

Overrides:

clone in class AbstractExprNode

Returns:

the cloned expression node

getValue

public final Value getValue()

Gets the value.

Returns:

the value

getEscapedValue

public String getEscapedValue()

Returns:

representation of value, escaped for use in a filter if required

setValue

public void setValue(Value value)

Sets the value of this node.

Parameters:

value - the value for this node

printToBuffer

public StringBuilder printToBuffer(StringBuilder buf)

Pretty prints this expression node along with annotation information.

Parameters:

buf - the buffer to print into

Returns:

the same buf argument returned for call chaining

printRefinementToBuffer

public StringBuilder printRefinementToBuffer(StringBuilder buf)

Description copied from class: AbstractExprNode

Default implementation for this method : just throw an exception.

Specified by:

printRefinementToBuffer in interface ExprNode

Overrides:

printRefinementToBuffer in class AbstractExprNode

Parameters:

buf - the buffer to append to.

Returns:

The buffer in which the refinement has been appended

Throws:

UnsupportedOperationException - if this node isn't a part of a refinement.

See Also:

ExprNode.printRefinementToBuffer(StringBuilder)

hashCode

public int hashCode()

Overrides:

hashCode in class LeafNode

Returns:

the instance's hash code

See Also:

Object.hashCode()

equals

public boolean equals(Object other)

Overrides:

equals in class LeafNode

Returns:

true if both objects are equal

See Also:

Object.equals(java.lang.Object)
