Method Detail

init

public void init(Object arg1)
          throws StandardException

Initializer for a BitConstantNode.

Overrides:

init in class QueryTreeNode

Parameters:

arg1 - A Bit containing the value of the constant OR The TypeId for the type of the node

Throws:

StandardException

init

public void init(Object arg1,
        Object arg2)
          throws StandardException

Description copied from class: QueryTreeNode

Initialize a query tree node.

Overrides:

init in class QueryTreeNode

Throws:

StandardException - Thrown on error

copyFrom

public void copyFrom(QueryTreeNode node)
              throws StandardException

Fill this node with a deep copy of the given node.

Overrides:

copyFrom in class ConstantNode

Throws:

StandardException

fromHexString

public static byte[] fromHexString(String s,
                   int offset,
                   int length)

Convert a hexidecimal string generated by toHexString() back into a byte array.

Parameters:

s - String to convert

offset - starting character (zero based) to convert.

length - number of characters to convert.

Returns:

the converted byte array. Returns null if the length is not a multiple of 2.
