=head1 NAME

Paws::DynamoDB::DeleteItem - Arguments for method DeleteItem on Paws::DynamoDB

=head1 DESCRIPTION

This class represents the parameters used for calling the method DeleteItem on the
Amazon DynamoDB service. Use the attributes of this class
as arguments to method DeleteItem.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to DeleteItem.

As an example:

  $service_obj->DeleteItem(Att1 => $value1, Att2 => $value2, ...);

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object.

=head1 ATTRIBUTES


=head2 ConditionalOperator => Str

This is a legacy parameter. Use C<ConditionExpression> instead. For
more information, see ConditionalOperator in the I<Amazon DynamoDB
Developer Guide>.

Valid values are: C<"AND">, C<"OR">

=head2 ConditionExpression => Str

A condition that must be satisfied in order for a conditional
C<DeleteItem> to succeed.

An expression can contain any of the following:

=over

=item *

Functions: C<attribute_exists | attribute_not_exists | attribute_type |
contains | begins_with | size>

These function names are case-sensitive.

=item *

Comparison operators: C<= | E<lt>E<gt> | E<lt> | E<gt> | E<lt>= |
E<gt>= | BETWEEN | IN>

=item *

Logical operators: C<AND | OR | NOT>

=back

For more information on condition expressions, see Specifying
Conditions in the I<Amazon DynamoDB Developer Guide>.



=head2 Expected => L<Paws::DynamoDB::ExpectedAttributeMap>

This is a legacy parameter. Use C<ConditionExpression> instead. For
more information, see Expected in the I<Amazon DynamoDB Developer
Guide>.



=head2 ExpressionAttributeNames => L<Paws::DynamoDB::ExpressionAttributeNameMap>

One or more substitution tokens for attribute names in an expression.
The following are some use cases for using C<ExpressionAttributeNames>:

=over

=item *

To access an attribute whose name conflicts with a DynamoDB reserved
word.

=item *

To create a placeholder for repeating occurrences of an attribute name
in an expression.

=item *

To prevent special characters in an attribute name from being
misinterpreted in an expression.

=back

Use the B<#> character in an expression to dereference an attribute
name. For example, consider the following attribute name:

=over

=item *

C<Percentile>

=back

The name of this attribute conflicts with a reserved word, so it cannot
be used directly in an expression. (For the complete list of reserved
words, see Reserved Words in the I<Amazon DynamoDB Developer Guide>).
To work around this, you could specify the following for
C<ExpressionAttributeNames>:

=over

=item *

C<{"#P":"Percentile"}>

=back

You could then use this substitution in an expression, as in this
example:

=over

=item *

C<#P = :val>

=back

Tokens that begin with the B<:> character are I<expression attribute
values>, which are placeholders for the actual value at runtime.

For more information on expression attribute names, see Accessing Item
Attributes in the I<Amazon DynamoDB Developer Guide>.



=head2 ExpressionAttributeValues => L<Paws::DynamoDB::ExpressionAttributeValueMap>

One or more values that can be substituted in an expression.

Use the B<:> (colon) character in an expression to dereference an
attribute value. For example, suppose that you wanted to check whether
the value of the I<ProductStatus> attribute was one of the following:

C<Available | Backordered | Discontinued>

You would first need to specify C<ExpressionAttributeValues> as
follows:

C<{ ":avail":{"S":"Available"}, ":back":{"S":"Backordered"},
":disc":{"S":"Discontinued"} }>

You could then use these values in an expression, such as this:

C<ProductStatus IN (:avail, :back, :disc)>

For more information on expression attribute values, see Specifying
Conditions in the I<Amazon DynamoDB Developer Guide>.



=head2 B<REQUIRED> Key => L<Paws::DynamoDB::Key>

A map of attribute names to C<AttributeValue> objects, representing the
primary key of the item to delete.

For the primary key, you must provide all of the attributes. For
example, with a simple primary key, you only need to provide a value
for the partition key. For a composite primary key, you must provide
values for both the partition key and the sort key.



=head2 ReturnConsumedCapacity => Str



Valid values are: C<"INDEXES">, C<"TOTAL">, C<"NONE">

=head2 ReturnItemCollectionMetrics => Str

Determines whether item collection metrics are returned. If set to
C<SIZE>, the response includes statistics about item collections, if
any, that were modified during the operation are returned in the
response. If set to C<NONE> (the default), no statistics are returned.

Valid values are: C<"SIZE">, C<"NONE">

=head2 ReturnValues => Str

Use C<ReturnValues> if you want to get the item attributes as they
appeared before they were deleted. For C<DeleteItem>, the valid values
are:

=over

=item *

C<NONE> - If C<ReturnValues> is not specified, or if its value is
C<NONE>, then nothing is returned. (This setting is the default for
C<ReturnValues>.)

=item *

C<ALL_OLD> - The content of the old item is returned.

=back

The C<ReturnValues> parameter is used by several DynamoDB operations;
however, C<DeleteItem> does not recognize any values other than C<NONE>
or C<ALL_OLD>.

Valid values are: C<"NONE">, C<"ALL_OLD">, C<"UPDATED_OLD">, C<"ALL_NEW">, C<"UPDATED_NEW">

=head2 B<REQUIRED> TableName => Str

The name of the table from which to delete the item.
