QueryTranslator

public QueryTranslator()

Method Detail

preProcess

protected void preProcess()

Called by super class to reset any objects.

isInitialDeclarator

protected boolean isInitialDeclarator()

True/false whether or not its the initial declarator. We care about this because we must know what the first one is for differentiating between the first declarator (the beginning of the query) and any other declarators (the connecting associations).

isArgument

protected boolean isArgument(java.lang.String name)

Returns true if the name is one of the arguments.

Returns:

boolean true if its an argument

inAOperationContextDeclaration

public void inAOperationContextDeclaration(org.ocltf.parser.node.AOperationContextDeclaration declaration)

Gets the information about the operation which is the context of this expression.

inAStandardDeclarator

public void inAStandardDeclarator(org.ocltf.parser.node.AStandardDeclarator declarator)

Helps out with 'includesAll', replaces the {1} in the expression fragment when a declarator is encountered (i.e. '| ')

inAPropertyCallExpression

public void inAPropertyCallExpression(org.ocltf.parser.node.APropertyCallExpression expression)

Override to handle any propertyCall expressions ( i.e. exists(), select(, etc.)

inALogicalExpressionTail

public void inALogicalExpressionTail(org.ocltf.parser.node.ALogicalExpressionTail logicalExpressionTail)

Override to deal with logical 'and, 'or', 'xor, ... expressions.

inARelationalExpressionTail

public void inARelationalExpressionTail(org.ocltf.parser.node.ARelationalExpressionTail relationalExpressionTail)

Override to deal with relational '<, '>', '=', ... expressions.

replaceFragment

protected java.lang.String replaceFragment(java.lang.String fragment,
                                           java.lang.String replacement,
                                           int index)

Checks to see if the replacement is an argument and if so replaces the {index} in the fragment with the 'argument' fragment from the template. Otherwise replaces the {index} with the passed in replacement value.

Parameters:

fragment - the fragment to perform replacement.

replacement - the replacement string

index - the index in the string to replace.

Returns:

String the fragment with any replacements.

postProcess

protected void postProcess()

Handles any final processing.

handleSubSelect

public void handleSubSelect(java.lang.String translation,
                            java.lang.Object node)

handleIsLike

public void handleIsLike(java.lang.String translation,
                         java.lang.Object node)

handleSelect

public void handleSelect(java.lang.String translation,
                         java.lang.Object node)

handleExists

public void handleExists(java.lang.String translation,
                         java.lang.Object node)

handleIsEmpty

public void handleIsEmpty(java.lang.String translation,
                          java.lang.Object node)

handleLogicalExpression

public void handleLogicalExpression(java.lang.String translation,
                                    java.lang.Object node)

handleRelationalExpression

public void handleRelationalExpression(java.lang.String translation,
                                       java.lang.Object node)
