Method Detail

and

public SignalEventQuery.FilterQuery and()

Description copied from interface: SignalEventQuery.IFilterLink

Adds an AND statement to the where condition.
Must be followed by other query conditions.

Note that and operations are always evaluated before or operations, e.g. the expression A OR B AND C is evaluated to A OR (B AND C). If you need to get (A OR B) AND C, then use the andOverall method.

Example A OR (B AND C):

SignalEventQuery.create().description().isEqual("A").or().description().isEqual("B")
  .and().name().isEqual("C");

SQL part: AND

Specified by:

and in interface SignalEventQuery.IFilterLink

Returns:

query for further composition

See Also:

SignalEventQuery.IFilterLink.and()

API:

This public API is available in IvyScript and Java. It has the visibility EXPERT.

and

public SignalEventQuery.FilterLink and(SignalEventQuery subQuery)

Description copied from interface: SignalEventQuery.IFilterLink

Adds and AND statement with the given filter subQuery. Only the where condition of the given subQuery is considered. All other parts are ignored. The whole where condition of the given filter subQuery is and-ed to the query as one term with brackets around it.

Note that and operations are always evaluated before or operations, e.g. the expression A OR B AND (subQuery) is evaluated to A OR (B AND (subQuery)). If you need to get (A OR B) AND (subQuery), then use the andOverall method.

Example A AND (B OR C):

SignalEventQuery.create().description().isEqual("A")
  .and(SignalEventQuery.create().name().isEqual("B").or().name().isEqual("C"));

SQL part: AND([subQueryWhereClause])

Specified by:

and in interface SignalEventQuery.IFilterLink

Parameters:

subQuery - query with a set of where conditions.

Returns:

query for further composition

See Also:

SignalEventQuery.IFilterLink.and(SignalEventQuery)

API:

This public API is available in IvyScript and Java. It has the visibility EXPERT.

andOverall

public SignalEventQuery.FilterQuery andOverall()

Description copied from interface: SignalEventQuery.IFilterLink

Adds an AND statement to the whole where condition configured before.
Must be followed by other query conditions.

Example (A OR B) AND C:

SignalEventQuery.create().description().isEqual("A").or().description().isEqual("B")
  .andOverall().name().isEqual("C");

Specified by:

andOverall in interface SignalEventQuery.IFilterLink

Returns:

query for further composition

public SignalEventQuery.FilterLink andOverall(SignalEventQuery subQuery)

Description copied from interface: SignalEventQuery.IFilterLink

Adds and AND statement with the given filter subQuery to the whole where condition configured before. Only the where condition of the given subQuery is considered. All other parts are ignored. The whole where condition of the given filter subQuery is and-ed to the query as one term with brackets around it.

Example (A OR B) AND (C OR D):

SignalEventQuery.create().description().isEqual("A").or().description().isEqual("B")
  .andOverall(SignalEventQuery.create().name().isEqual("C").or().name().isEqual("D"));

SQL part: AND([subQueryWhereClause])

Specified by:

andOverall in interface SignalEventQuery.IFilterLink

Parameters:

subQuery - query with a set of where conditions.

Returns:

public SignalEventQuery.FilterQuery or()

Description copied from interface: SignalEventQuery.IFilterLink

Adds an OR statement to the where condition.
Must be followed by other query conditions.

Note that and operations are evaluated before or operations. E.g. the expression A and B or C is evaluated like (A and B) or C

SQL part: OR

Specified by:

or in interface SignalEventQuery.IFilterLink

Returns:

query for further composition

or

public SignalEventQuery.FilterLink or(SignalEventQuery subQuery)

Description copied from interface: SignalEventQuery.IFilterLink

Adds and OR statement with the given filter subQuery.
Only the where condition of the given subQuery is considered. All other parts are ignored. The whole where condition of the given filter subQuery is or-ed to the query as one term with brackets around it.

Note that and operations are always evaluated before or operations, e.g. the expression A AND B OR C is evaluated to (A AND B) OR C. If you need to get A AND (B OR C), then use this method to add a sub query (B OR C) with a AND operation to the current query (A).

SQL part: OR([subQueryWhereClause])

Specified by:

or in interface SignalEventQuery.IFilterLink

Parameters:

subQuery - query with a set of where conditions.

Returns:

query for further composition
