Parameters:

literal - the query literal to convert to an operand; must not be null or empty.

Method Detail

getName

public String getName()

Description copied from interface: Operand

The name that represents this Operand.

Specified by:

getName in interface Operand

Returns:

the name of the operand, null if the operand is unnamed. If an operand is unnamed then it likely represents literal values (such as Strings or Longs).

getDisplayString

public String getDisplayString()

Description copied from interface: Operand

Produces the unexpanded representation of the Operand. In the case of a function operand this would be the function as represented in the Query (i.e. group(jira-users)).

Specified by:

getDisplayString in interface Operand

Returns:

a string that represents this operand as represented in the JQL query string.

accept

public <R> R accept(OperandVisitor<R> visitor)

Description copied from interface: Operand

Allows us to perform operations over the operand based on the passed in visitor. This method calls the visit method on the visitor with this reference.

Specified by:

accept in interface Operand

Type Parameters:

R - the return type for the visitor.

Parameters:

visitor - the visitor to accept.

Returns:

the result of the visit operation who's type is specified by the incomming visitor.

getLongValue

public Long getLongValue()

getStringValue

public String getStringValue()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString
