Method Detail

categorizeMethods

protected void categorizeMethods()

Reads all known methods and sorts them by name into specific Collections for further processing.

Overrides:

categorizeMethods in class AbstractMethodHelper

isQueryPrefetchEnabled

public boolean isQueryPrefetchEnabled(Method method)

Returns true if prefetch is enabled for the specified method, false otherwise. Prefetch is enabled by default.

Specified by:

isQueryPrefetchEnabled in class AbstractMethodHelper

Parameters:

method - the java.lang.reflect.Method object used to find the prefetch setting.

Returns:

a boolean representing the prefetch setting

getJDOFilterExpression

public String getJDOFilterExpression(Method method)

Gets the jdo filter expression associated with the specified method if it exists. Note that this method should only be used for CMP 1.1 - use AbstractMethodHelper.getQueryString(java.lang.reflect.Method) for CMP 2.0.

Specified by:

getJDOFilterExpression in class AbstractMethodHelper

Parameters:

method - the java.lang.reflect.Method object used to find the query filter

Returns:

the jdo filter expression

getJDOParameterDeclaration

public String getJDOParameterDeclaration(Method method)

Gets the jdo parameter declaration associated with the specified method if it exists. Note that this method should only be used for CMP 1.1 - use AbstractMethodHelper.getQueryString(java.lang.reflect.Method) for CMP 2.0.

Specified by:

getJDOParameterDeclaration in class AbstractMethodHelper

Parameters:

method - the java.lang.reflect.Method object used to find the parameter declaration

Returns:

the jdo parameter declaration

getJDOVariableDeclaration

public String getJDOVariableDeclaration(Method method)

Gets the jdo variables declaration associated with the specified method if it exists. Note that this method should only be used for CMP 1.1 - use AbstractMethodHelper.getQueryString(java.lang.reflect.Method) for CMP 2.0.

Specified by:

getJDOVariableDeclaration in class AbstractMethodHelper

Parameters:

method - the java.lang.reflect.Method object used to find the parameter declaration

Returns:

the jdo variables declaration

getJDOOrderingSpecification

public String getJDOOrderingSpecification(Method method)

Gets the jdo ordering specification associated with the specified method if it exists. Note that this method should only be used for CMP 1.1 - use AbstractMethodHelper.getQueryString(java.lang.reflect.Method) for CMP 2.0.

Specified by:

getJDOOrderingSpecification in class AbstractMethodHelper

Parameters:

method - the java.lang.reflect.Method object used to find the parameter declaration

Returns:

the jdo ordering specification
