Constructor Details

PgEventTrigger

public PgEventTrigger(String name)

Creates a new PostgreSQL event trigger.

Parameters:

name - trigger name

Method Details

getCreationSQL

public void getCreationSQL(SQLScript script)

Description copied from interface: IStatement

Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.

Parameters:

script - the SQL script to append creation statements to

appendAlterSQL

public ObjectState appendAlterSQL(IStatement newCondition,
 SQLScript script)

Description copied from interface: IStatement

Fill script with object changes and return change type

Parameters:

newCondition - new object state

script - script to collect changes

Returns:

object change type

getTypeName

public String getTypeName()

Description copied from interface: IStatement

Gets the type name of this statement for SQL generation.

Returns:

the type name

getStatementType

public DbObjType getStatementType()

Description copied from interface: IStatement

Gets the type of this database object.

Returns:

the database object type

setExecutable

public void setExecutable(String executable)

addTag

public void addTag(String tag)

Adds a command tag that this trigger should respond to.

Parameters:

tag - command tag to add

setEvent

public void setEvent(String event)

setMode

public void setMode(String mode)

computeHash

public void computeHash(Hasher hasher)

Description copied from interface: IHashable

Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.

Parameters:

hasher - the hasher instance to use for hash computation

compare

public boolean compare(IStatement obj)

Description copied from class: AbstractStatement

This method does not account for nested child PgStatements. Shallow version of AbstractStatement.equals(Object)

Specified by:

compare in interface IStatement

Overrides:

compare in class AbstractStatement
