Constructor Detail

SimpleNode

protected SimpleNode(java.lang.String attribute,
                     Value<T> value,
                     AssertionType assertionType)

Creates a new SimpleNode object.

Parameters:

attribute - the attribute name

value - the value to test for

assertionType - the type of assertion represented by this ExprNode

Method Detail

clone

public ExprNode clone()

Clone the Node

Specified by:

clone in interface ExprNode

Overrides:

clone in class LeafNode

Returns:

the clone

getValue

public final Value<T> getValue()

Gets the value.

Returns:

the value

getEscapedValue

public Value<?> getEscapedValue()

Returns:

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

setValue

public void setValue(Value<T> value)

Sets the value of this node.

Parameters:

value - the value for this node

printToBuffer

public java.lang.StringBuilder printToBuffer(java.lang.StringBuilder buf)

Pretty prints this expression node along with annotation information. TODO - perhaps this belong in some utility class?

Parameters:

buf - the buffer to print into

Returns:

the same buf argument returned for call chaining

printRefinementToBuffer

public java.lang.StringBuilder printRefinementToBuffer(java.lang.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:

java.lang.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(java.lang.Object other)

Overrides:

equals in class LeafNode

Returns:

true if both objects are equal

See Also:

Object.equals(Object)
