Method Detail

getHead

MetricalLpcfgHead getHead()

Get the head of this lpcfg node. This implements the lexicalization of the lpcfg.

Returns:

The head of this lpcfg node, relative to the sub beat length, where the sub beat length is 1.

getLength

int getLength()

Get the length of this node, measured in sub beats.

Returns:

The length of this node in sub beats.

getTerminal

MetricalLpcfgTerminal getTerminal()

Get the terminal at this level of the tree.

Returns:

The terminal at this node.

isEmpty

boolean isEmpty()

Get if this node is empty or not.

Returns:

True if this node contains no notes. False otherwise.

startsWithRest

boolean startsWithRest()

Get if this node starts with a REST or not.

Returns:

True if this node starts with a REST. False otherwise.

deepCopy

MetricalLpcfgNode deepCopy()

Get a deep copy of this node. Each node needs this because we sometimes need a deep copy of the entire tree.

Returns:

A deep copy of this node.

toStringPretty

java.lang.String toStringPretty(int depth,
                              java.lang.String tab)

Print the given node recursively in a pretty format.

Parameters:

depth - The depth of this node.

tab - The tab String to indent tree levels.

Returns:

This node in a pretty recursive format.
