java.lang.Object

org.eclipse.persistence.services.DevelopmentServices

Direct Known Subclasses:

MBeanDevelopmentServices

public class DevelopmentServices
extends java.lang.Object

Purpose: Provide a dynamic interface into the EclipseLink Identity Map Manager.

Description: This class is meant to provide a framework for gaining access to configuration and statistics of the EclipseLink Cache during runtime. It will provide the basis for development of a JMX service and possibly other frameworks.

Method Detail

initializeIdentityMap

public void initializeIdentityMap(java.lang.String className)
                           throws java.lang.ClassNotFoundException

This method is used to clear the contents of a particular identity map. Users should be aware that if any of these objects are in use when this action is completed they will lose object identity.

Parameters:

className - the fully qualified name of the class for which the identity map should be cleared.

Throws:

java.lang.ClassNotFoundException - thrown then the IdenityMap for that class name could not be found

initializeAllIdentityMaps

public void initializeAllIdentityMaps()

This method is used to clear the contents of all identity maps. Users should be aware that if any of these objects are in use when this action is completed they will lose object identity.

setIdentityMapForClass

public void setIdentityMapForClass(java.lang.String className,
                                   java.lang.String identityMapClassType,
                                   int maxSize)
                            throws java.lang.ClassNotFoundException

This method will be used to set a new type of identity map for a particular class type. If objects of that class type are in use loss of object identity will result. For prevention client may wish to initialize all identity maps first.

Parameters:

className - the fully qualified className to set the identity map for.

identityMapClassType - the fully qualified class name of the new identity map type.

maxSize - the maximum size to be specified for the new identity map.

Throws:

java.lang.ClassNotFoundException - thrown then the IdenityMap for that class name could not be found

refreshProject

public void refreshProject(java.lang.String projectFilePath)

This method used to reset a project in a session. All connected clients will get errors. project must be of the xml type. This attribute will not be stored on a save.

Parameters:

projectFilePath - the filename of the project xml file to build the new project from.

updateCacheSize

public void updateCacheSize(java.lang.String className,
                            int newSize)
                     throws java.lang.ClassNotFoundException

This method is used to update the cache size of a particular Identity Map

Parameters:

className - the name of the class for which to update the identity map size.

Throws:

java.lang.ClassNotFoundException - thrown then the IdenityMap for that class name could not be found

setShouldBindAllParameters

public void setShouldBindAllParameters(boolean shouldBindAllParameters)

This method is used to control if All parameters should be bound

getShouldBindAllParameters

public boolean getShouldBindAllParameters()

Method returns if all Parameters should be bound or not

setStringBindingSize

public void setStringBindingSize(int size)

Sets the size of strings after which they will be bound into the statement

getStringBindingSize

public int getStringBindingSize()

Return the size of strings after which will be bound into the statement

setUsesBatchWriting

public void setUsesBatchWriting(boolean usesBatchWriting)

This method is used to turn on EclipseLink Batch Writing. Please note that toggling this setting while a transaction is open may result in unordered sql statements or loss of statements. Also please note that EclipseLink Batch Writing may not work with all JDBC Drivers

getUsesBatchWriting

public boolean getUsesBatchWriting()

This method will return if batchWriting is in use or not.

setUsesJDBCBatchWriting

public void setUsesJDBCBatchWriting(boolean usesJDBCBatchWriting)

This method is used to turn on JDBC Batch Writing. Please note that toggling this setting while a transaction is open may result in mis-ordered sql statements or loss of statements.

getUsesJDBCBatchWriting

public boolean getUsesJDBCBatchWriting()

This method will return if batchWriting is in use or not.

setUsesByteArrayBinding

public void setUsesByteArrayBinding(boolean usesByteArrayBinding)

This method allows control of whether byte arrays should be bound into the statement or not. Toggling this attribute while an SQL statement is being built, or if you are caching statements, will result in errors.

getUsesByteArrayBinding

public boolean getUsesByteArrayBinding()

Shows if Byte Array Binding is turned on or not

setUsesNativeSQL

public void setUsesNativeSQL(boolean usesNativeSQL)

This method allows the client to set if Native SQL should be used.

getUsesNativeSQL

public boolean getUsesNativeSQL()

Shows if native SQL is being used

setUsesStreamsForBinding

public void setUsesStreamsForBinding(boolean usesStreamsForBinding)

This method is used to set if streams should be used for binding. Please note that toggling this attribute while a statement is being built will result in errors.

getUsesStreamsForBinding

public boolean getUsesStreamsForBinding()

This method indicates if streams are being used for binding

setUsesStringBinding

public void setUsesStringBinding(boolean usesStringBinding)

Allows the client to set if String should be bound into the statement or not. Please note that toggling this attribute while a statement is being built, or if statement caching is being used, will result in errors.
