Function Documentation

Bboolco()

native BExprTree org.endurox.AtmiCtx.Bboolco

(

String

expr

)

Compile boolean expression. For more information see Bboolco(3) manpage

Parameters

expr	UBF boolean expression

Returns

Compiled boolean expression handler

Exceptions

UbfBALIGNERRException	Corrupted buffer or pointing to not aligned memory area.
UbfBNOTFLDException	Buffer not fielded, not correctly allocated or corrupted.
UbfBBADFLDException	Invalid field id passed.
UbfBNOTPRESException	Field not present.
UbfFMALLOCException	Malloc failed.
UbfBSYNTAXException	Synax error in script.
UbfBBADNAMEException	Bad field name specified.

Bboolpr()

native void org.endurox.AtmiCtx.Bboolpr	(	BExprTree	cexpr,
		OutputStream	ostream
	)

Print compiled expression to output stream. For more information see Bboolpr(3) manpage

Parameters

cexpr	compiled expression
ostream	output stream. write(byte[] bytes) is used for printing the output.

Bboolsetcbf()

void org.endurox.AtmiCtx.Bboolsetcbf	(	String	funcname,
		Bboolcbf	callback
	)

Set callback function from the expression, so that this function can be referenced/called from the compiled script/evaluated UBF boolean expression script. This function is not thread safe. meaning that any other thread shall not execute Boolean expressions while the callback are being registered. The function registers the callbacks at the java side into hashmap. and registration is done at C side too. The mapping is done in a singleton as it might be used by different contexts. For more information see Bboolsetcbf(3) manpage.

Parameters

funcname	function name (C style function name)
callback	interface to callback object

Exceptions

UbfBBADNAMEException

Invalid function name. See Bboolsetcbf(3) manpage.
