Method Detail

getRuntimeEnv

protected IRuntimeEnv getRuntimeEnv()

isValuesAnArray

protected static boolean isValuesAnArray(IOpenClass paramType)

Checks if type values are represented as array of elements.

Parameters:

paramType - Parameter type.

Returns:

true if paramType represents array

buildGroupKey

public ColumnDescriptor.ColumnGroupKey buildGroupKey()

getField

protected IOpenField getField()

getColumnValue

public Object getColumnValue(Object target)

getDisplayName

public String getDisplayName()

getLiteral

public Object getLiteral(IOpenClass paramType,
                         ILogicalTable valuesTable,
                         OpenlToolAdaptor ota)
                  throws SyntaxNodeException

Method is using to load data. Is used when data table is represents AS a constructor (see isConstructor()).

Throws:

SyntaxNodeException

getName

getType

public IOpenClass getType()

getUniqueIndex

public Map<String,Integer> getUniqueIndex(ITable table,
                                                int idx,
                                                IBindingContext cxt)

isConstructor

Throws:

SyntaxNodeException
