Method Detail

fillMathSignsMap

protected void fillMathSignsMap()

declareCSymbolAsVariable

public void declareCSymbolAsVariable(java.lang.String name)

declareCSymbolAsFunction

public void declareCSymbolAsFunction(Function function)

parse

public int parse(java.lang.String xmlString)

Specified by:

parse in interface Parser

parse

public int parse(org.w3c.dom.Element math)

buildTree

public void buildTree()

buildAstTree

protected Node buildAstTree(org.w3c.dom.Node xmlRoot)

processMATH

protected Node processMATH(org.w3c.dom.Node domNodeRoot)

processNode

protected Node processNode(org.w3c.dom.Node domNode)

processAPPLY

protected AstFunNode processAPPLY(org.w3c.dom.Node domNodeRoot)

-tag is like serialized function call. The first child element of apply is function name (see mathSignsMap, also may be ). Then, various qualifier tags can be met. (we concern only , , ) Finally, arguments of the function can also be presented. (, , , ) p.s. is like on-the-fly declaration (not definition)

processCI

protected AstVarNode processCI(org.w3c.dom.Node domNode)

Atrribute "type" is ignored.

processPI

protected AstConstant processPI(org.w3c.dom.Node domNodePI_EXP)

processEXP

protected AstConstant processEXP(org.w3c.dom.Node domNodeEXP)

processTRUE

protected AstConstant processTRUE()

processFALSE

protected AstConstant processFALSE()

processPIECEWISE

protected AstPiecewise processPIECEWISE(org.w3c.dom.Node domNodePW)

processPIECE

protected AstPiece processPIECE(org.w3c.dom.Node domNodePiece)

processCN

protected AstConstant processCN(org.w3c.dom.Element cnElement)

We assume that attribute "type" can only be "integer", "real" or "e-notation". Attribute "base" is ignored.

processCSYMBOL

protected Node processCSYMBOL(org.w3c.dom.Node domNode)

processFunction

protected AstFunNode processFunction(org.w3c.dom.Node domNode)
