Method Details

setInvokerInterceptor

public void setInvokerInterceptor(FunctionInvokerInterceptor invokerInterceptor)

runtimeConfiguration

public ParamEngineRuntimeConfig runtimeConfiguration()

Description copied from interface: ParamEngine

Return runtime configuration of this instance of parameter engine.

Specified by:

runtimeConfiguration in interface ParamEngine

Returns:

runtime config

getDigest

public String getDigest(Type type,
 String elementCode)

Description copied from interface: ParamEngine

Return digest of one of given Parameter/Funcion/Literal value

Specified by:

getDigest in interface ParamEngine

Parameters:

type - of Higson element to calculate its digest

elementCode - code of parameter/function or literal value

Returns:

digest as string of given element or null, if digest is not available.

get

public ParamValue get(String paramName,
 ParamContext ctx)

Description copied from interface: ParamEngine

Return submatrix of parameter rows that match values from context. Remember, that to use dynamic context levels need to have defined levelCreators.

Specified by:

get in interface ParamEngine

Parameters:

paramName - name of parameter to search

ctx - evaluation context

Returns:

resulting submatrix

get

public ParamValue get(String paramName,
 Object... inputLevels)

Description copied from interface: ParamEngine

Return submatrix of parameter rows that match provided query values. Input levels array should have length equal to parameters input levels count.

Specified by:

get in interface ParamEngine

Parameters:

paramName - name of parameter to search

inputLevels - values to match against each input level

Returns:

resulting submatrix

callFunction

public Object callFunction(String functionName,
 Object... args)

Description copied from interface: ParamEngine

Use function engine to call function registered under provided name, passing provided invocation arguments.

Specified by:

callFunction in interface ParamEngine

Parameters:

functionName - name of function to run

args - function invocation arguments

Returns:

invocation result, null for void functions

callEvaluatedFunction

public Object callEvaluatedFunction(String paramName,
 ParamContext ctx,
 Object... args)

Description copied from interface: ParamEngine

Evaluate parameter using provided context and use returned value retrieved using ParamValue.get() as name of function to call with provided arguments.

Specified by:

callEvaluatedFunction in interface ParamEngine

Parameters:

paramName - name of parameter to evaluate

ctx - evaluation context

args - function invocation arguments

Returns:

invocation result, null for void functions

setProperties

public void setProperties(Properties properties)

Specified by:

setProperties in interface PropertiesAware
