Constructor Details

DeployTableJoin

public DeployTableJoin()

Create a DeployTableJoin.

Method Details

toString

public String toString()

Overrides:

toString in class Object

hasJoinColumns

public boolean hasJoinColumns()

Return true if the JoinOnPair have been set.

setColumns

public void setColumns(DeployTableJoinColumn[] cols,
 boolean reverse)

Copy all the columns to this join potentially reversing the columns.

addJoinColumn

public void addJoinColumn(DeployTableJoinColumn pair)

Add a join pair

addJoinColumn

public void addJoinColumn(io.ebeaninternal.server.deploy.parse.DeployUtil deploy,
 boolean order,
 jakarta.persistence.JoinColumn jc,
 BeanTable beanTable)

Add a JoinColumn

The order is generally true for OneToMany and false for ManyToOne relationships.

addJoinColumn

public void addJoinColumn(io.ebeaninternal.server.deploy.parse.DeployUtil util,
 boolean order,
 jakarta.persistence.JoinColumn[] jcArray,
 BeanTable beanTable)

Add a JoinColumn array.

addJoinColumn

public void addJoinColumn(io.ebeaninternal.server.deploy.parse.DeployUtil util,
 boolean order,
 Set<jakarta.persistence.JoinColumn> joinColumns,
 BeanTable beanTable)

Add a JoinColumn set.

columns

public DeployTableJoinColumn[] columns()

Return the join columns.

getTable

public String getTable()

Return the joined table name.

setTable

public void setTable(String table)

set the joined table name.

getType

public SqlJoinType getType()

Return the type of join. LEFT OUTER JOIN etc.

setType

public void setType(SqlJoinType type)

getExtraWhere

public String getExtraWhere()

Returns the clause of an extra @Where annotation.

setExtraWhere

public void setExtraWhere(String extraWhere)

createInverse

public DeployTableJoin createInverse(String tableName)

copyTo

public void copyTo(DeployTableJoin destJoin,
 boolean reverse,
 String tableName)

copyWithoutType

public void copyWithoutType(DeployTableJoin destJoin,
 boolean reverse,
 String tableName)

clear

public void clear()

Clear the join columns due to an implied mappedBy.

Effectively prior to clear this was considered a unidirectional OneToMany and the foreign key was defined by naming convention. Clearing this means that it uses the foreign key as defined by the implied mappedBy property (the only ManyToOne that maps back to the parent (that holds the OneToMany).
