Returns a keyChain for aSource (should be a String or existing RMKeyChain).

getAssignments

public static java.util.Map getAssignments()

operand

public byte operand()

Returns the top level operand of the keychain.

setNextNode

public void setNextNode(RMKeyChain nn)

Sets the next node in the keychain.

setLastNode

public void setLastNode(RMKeyChain ln)

Sets the last node in the keychain.

value

public java.lang.Object value()

Returns the value of the keychain.

public java.lang.String getChildString(int i)

Returns the child at the given index in the keychain as a string.

getChildKeyChain

public RMKeyChain getChildKeyChain(int i)

Returns the child at the given index in the keychain as a keychain.

addChild

public void addChild(java.lang.Object child)

Adds a child to the end of the keychain's child list.

valueForKeyChain

public static java.lang.Object valueForKeyChain(java.lang.Object anObj,
