getVariable

public org.agrona.DirectBuffer getVariable(long scopeKey,
                                           org.agrona.DirectBuffer name)

Find the variable with the given name. If the variable is not present in the given scope then it looks in the parent scope and continues until it is found.

Parameters:

scopeKey - the key of the variable scope to start from

name - the name of the variable

Returns:

the value of the variable, or null if it is not present in the variable scope

getVariable

public org.agrona.DirectBuffer getVariable(long scopeKey,
                                           org.agrona.DirectBuffer name,

                                           int nameLength)

Find the variable with the given name. If the variable is not present in the given scope then it looks in the parent scope and continues until it is found.

Parameters:

scopeKey - the key of the variable scope to start from

name - the buffer that contains the name of the variable

nameOffset - the offset of name in the buffer

nameLength - the length of the name in the buffer

Returns:

the value of the variable, or null if it is not present in the variable scope
