ConstraintDescriptorList

public ConstraintDescriptorList()

Method Detail

setScanned

public void setScanned(boolean scanned)

Mark whether or not the underlying system table has been scanned. (If a table does not have any constraints then the size of its CDL will always be 0. We used these get/set methods to determine when we need to scan the table.

Parameters:

scanned - Whether or not the underlying system table has been scanned.

getScanned

public boolean getScanned()

Return whether or not the underlying system table has been scanned.

Returns:

Where or not the underlying system table has been scanned.

getConstraintDescriptor

public ConstraintDescriptor getConstraintDescriptor(UUID indexUUID)

Get the ConstraintDescriptor with the matching UUID String for the backing index.

Parameters:

indexUUID - The UUID for the backing index.

Returns:

The matching ConstraintDescriptor.

getConstraintDescriptorById

public ConstraintDescriptor getConstraintDescriptorById(UUID uuid)

Get the ConstraintDescriptor with the matching constraint id.

Parameters:

uuid - The constraint id.

Returns:

The matching ConstraintDescriptor.

dropConstraintDescriptorById

public ConstraintDescriptor dropConstraintDescriptorById(UUID uuid)

Drop the constraint with the given UUID.

Parameters:

uuid - The constraint id.

Returns:

The matching ConstraintDescriptor.

getConstraintDescriptorByName

public ConstraintDescriptor getConstraintDescriptorByName(SchemaDescriptor sd,
                                                          java.lang.String name)

Get the ConstraintDescriptor with the matching constraint name.

Parameters:

sd - The constraint schema descriptor.

name - The constraint name.

Returns:

The matching ConstraintDescriptor.

getPrimaryKey

public ReferencedKeyConstraintDescriptor getPrimaryKey()

Get the ConstraintDescriptor with the matching constraint name.

Returns:

The matching ConstraintDescriptor.

getConstraintDescriptorList

public ConstraintDescriptorList getConstraintDescriptorList(boolean enabled)

Return a list of constraints where enabled is as passed in.

Parameters:

enabled - true or false

Returns:

a constraint descriptor list built from this. Always a new list even if all the elements in this were of the correct type (i.e. not optimized for the case where every element is desired).

elementAt

public ConstraintDescriptor elementAt(int n)

Return the nth (0-based) element in the list.

Parameters:

n - Which element to return.

Returns:

The nth element in the list.

getSubList

public ConstraintDescriptorList getSubList(int type)

Return a ConstraintDescriptorList containing the ConstraintDescriptors of the specified type that are in this list.

Parameters:

type - The constraint type.

Returns:

A ConstraintDescriptorList containing the ConstraintDescriptors of the specified type that are in this list.
