Constructors

PgILikeExpression(SqlExpression, SqlExpression, SqlExpression?, RelationalTypeMapping?)

Constructs a PgILikeExpression.

public PgILikeExpression(SqlExpression match, SqlExpression pattern, SqlExpression? escapeChar, RelationalTypeMapping? typeMapping)

Parameters

match SqlExpression

The expression to match.

pattern SqlExpression

The pattern to match.

escapeChar SqlExpression

The escape character to use in pattern.

typeMapping RelationalTypeMapping

The RelationalTypeMapping associated with the expression.

Exceptions

ArgumentNullException

Properties

EscapeChar

The escape character to use in Pattern.

public virtual SqlExpression? EscapeChar { get; }

Property Value

SqlExpression

Match

The match expression.

public virtual SqlExpression Match { get; }

Property Value

SqlExpression

Pattern

The pattern to match.

public virtual SqlExpression Pattern { get; }

Property Value

SqlExpression

Methods

Equals(PgILikeExpression?)

Indicates whether the current object is equal to another object of the same type.

public virtual bool Equals(PgILikeExpression? other)

Parameters

other PgILikeExpression

An object to compare with this object.

Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Determines whether the specified object is equal to the current object.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current object.

Returns

bool

true if the specified object is equal to the current object; otherwise, false.

GetHashCode()

Serves as the default hash function.

public override int GetHashCode()

Returns

int

A hash code for the current object.

Print(ExpressionPrinter)

Creates a printable string representation of the given expression using ExpressionPrinter.

protected override void Print(ExpressionPrinter expressionPrinter)

Parameters

expressionPrinter ExpressionPrinter

The expression printer to use.

Quote()

Quotes the expression; that is, returns an expression that, when evaluated, would construct an expression identical to this one. Used to generate code for precompiled queries, which reconstructs this expression.

public override Expression Quote()

Returns

Expression

ToString()

Returns a textual representation of the Expression.

public override string ToString()

Returns

string

A textual representation of the Expression.

Update(SqlExpression, SqlExpression, SqlExpression?)

Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.

public virtual PgILikeExpression Update(SqlExpression match, SqlExpression pattern, SqlExpression? escapeChar)

Parameters

match SqlExpression
pattern SqlExpression
escapeChar SqlExpression

Returns

PgILikeExpression

VisitChildren(ExpressionVisitor)

Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.

protected override Expression VisitChildren(ExpressionVisitor visitor)

Parameters

visitor ExpressionVisitor

An instance of Func<T, TResult>.

Returns

Expression

The expression being visited, or an expression which should replace it in the tree.
