Methods

NameDescription
and(keyCond)Conjunction between two conditions.
renderTemplate()Renders the key condition to a VTL string.
static beginsWith(keyName, arg)Condition (k, arg).
static between(keyName, arg1, arg2)Condition k BETWEEN arg1 AND arg2, true if k >= arg1 and k <= arg2.
static eq(keyName, arg)Condition k = arg, true if the key attribute k is equal to the Query argument.
static ge(keyName, arg)Condition k >= arg, true if the key attribute k is greater or equal to the Query argument.
static gt(keyName, arg)Condition k > arg, true if the key attribute k is greater than the the Query argument.

Condition k = arg, true if the key attribute k is equal to the Query argument.

static ge(keyName, arg)

public static ge(keyName: string, arg: string): KeyCondition

Condition k >= arg, true if the key attribute k is greater or equal to the Query argument.

static gt(keyName, arg)

public static gt(keyName: string, arg: string): KeyCondition

Parameters

  • keyName string
  • arg string

Returns

Condition k > arg, true if the key attribute k is greater than the the Query argument.

static le(keyName, arg)

public static le(keyName: string, arg: string): KeyCondition

Parameters

  • keyName string
  • arg string

Returns

Condition k <= arg, true if the key attribute k is less than or equal to the Query argument.

static lt(keyName, arg)

public static lt(keyName: string, arg: string): KeyCondition

Parameters

  • keyName string
