Constructor Detail

QueryCondition

public QueryCondition()

Constructor for JPA entity.

QueryCondition

public QueryCondition(Query query,
                      QueryParenthesis parenthesisOpen,
                      String field,
                      QueryComparisonOperator comparisonOperator,
                      String value,
                      QueryParenthesis parenthesisClose,
                      QueryBooleanOperator booleanOperator,
                      Integer position)

Constructs new query condition.

Parameters:

query - query

parenthesisOpen - open parenthesis

field - field name

comparisonOperator - comparison operator

value - value

parenthesisClose - close parenthesis

booleanOperator - boolean operator

position - position

Method Detail

getQuery

public Query getQuery()

Returns:

query condition parent (query).

getParenthesisOpen

public QueryParenthesis getParenthesisOpen()

Returns:

query condition open parenthesis.

getField

public String getField()

Returns:

query condition field name.

getComparisonOperator

public QueryComparisonOperator getComparisonOperator()

Returns:

query condition comparison operator.

getValue

public String getValue()

Returns:

query condition value.

getParenthesisClose

public QueryParenthesis getParenthesisClose()

Returns:

query condition close parenthesis.

getBooleanOperator

public QueryBooleanOperator getBooleanOperator()

Returns:

query condition boolean operator.

getPosition

public Integer getPosition()

Returns:

query condition position for execution.

toString

public String toString()

Overrides:

toString in class Object

Returns:

query condition as stirng

getComparisonOperator

public QueryComparisonOperator getComparisonOperator(String comparisonOperator)

Convert comparison operator to enum from string

Parameters:

comparisonOperator - comparison operator

Returns:

query comparison operator

setQuery

public void setQuery(Query query)

setParenthesisOpen

public void setParenthesisOpen(QueryParenthesis parenthesisOpen)

setField

public void setField(String field)

setComparisonOperator

public void setComparisonOperator(QueryComparisonOperator comparisonOperator)

setValue

public void setValue(String value)

setParenthesisClose

public void setParenthesisClose(QueryParenthesis parenthesisClose)

setBooleanOperator

public void setBooleanOperator(QueryBooleanOperator booleanOperator)

setPosition

public void setPosition(Integer position)

compareTo

public int compareTo(QueryCondition o)

Specified by:

compareTo in interface Comparable<QueryCondition>

equals

public boolean equals(Object obj)

Override "equals(Object obj)" to comply with the contract of the "compareTo(T o)" method.

• It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)).

Overrides:

equals in class Object

See Also:

Comparable.compareTo(Object), Object.hashCode(), Object.equals(Object)

hashCode

public int hashCode()

This class overrides "equals()" and should therefore also override "hashCode()".

• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results.

Overrides:

hashCode in class Object

Comparable.compareTo(Object), Object.hashCode(), Object.equals(Object)
