Constructor Detail

FastRulesBuilder

public FastRulesBuilder(MOTPipeInterface pipe)

Initialize a new FastRulesBuilder with a MOT pipe

Parameters:

pipe - The pipe used during rules compilation

FastRulesBuilder

public FastRulesBuilder()

Initialize a new FastRulesBuilder for checking rules syntax

Method Detail

checkRuleSyntax

public boolean checkRuleSyntax(java.lang.String rule)

Check a rule syntax

Parameters:

rule -

Returns:

false if the rule is syntactically invalid, call getErrorMessage() for details

loadFromXML

public void loadFromXML(java.lang.String inputPath)
                 throws java.lang.Exception

Throws:

java.lang.Exception

loadFromDefinition

public void loadFromDefinition(FastRulesDefinition def)
                        throws InvalidFastRuleException

Throws:

InvalidFastRuleException

loadFromDefinitionIgnoringInvalidRules

public int loadFromDefinitionIgnoringInvalidRules(FastRulesDefinition def)

compile

public boolean compile(FastRulesDefinition def,
                       java.lang.String outputDir)
                throws InvalidFastRuleException

Compile a set of rules to a binary format

Parameters:

def - The source rules

outputDir - path to the target directory for binaries

Returns:

true if compilation is successful

Throws:

InvalidFastRuleException

compileValidRules

public int compileValidRules(FastRulesDefinition def,
                             java.lang.String outputDir)

Compiles a set of rules to a binary format. Doesn't interrupt if an invalid rule is found, just ignores it.

Parameters:

def - The source rules

outputDir - path to the target directory for binaries

Returns:

0 if all ok, -1 if compilation fails (all ko) otherwise the count of invalid rules

compile

public boolean compile(java.lang.String outputDir)

Compile a set of rules to a binary format

Parameters:

outputDir - path to the target directory for binaries
