|
inherited |

protectedinherited |
Check if a region is known by its name.
| string | $region |
| void | Coding Exception thrown if the region is not known |
|
inherited |
Create all the block instances for all the blocks that were loaded by load_blocks.
This is used, for example, to ensure that all blocks get a chance to initialise themselves via the block_base::specialize() method, before any output is done.
It is also used to create any blocks that are "requiredbytheme" by the current theme. These blocks that are auto-created have requiredbytheme set on the block instance so they are only visible on themes that require them.

|
inherited |
Get the region name of the region blocks are added to by default.

|
inherited |
Get an array of all of the installed blocks.
| array | contents of the block table. |
|
protectedinherited |
Helper method used by get_content_for_region.
| string | $region | region name |
| float | $weight | weight. May be fractional, since you may want to move a block between ones with weight 2 and 3, say ($weight would be 2.5). |
| string | URL for moving block $this->movingblock to this position. |
|
inherited |
Getter methods =============================================================.
Get an array of all region names on this page where a block may appear
| array | the internal names of the regions on this page where block may appear. |
|
inherited |

|
staticinherited |
Get the list of "protected" blocks via admin block manager ui.
| array | names of block types that cannot be added or deleted. E.g. array('navigation','settings'). |
|
inherited |
Given a block name, find out of any of them are currently present in the page.
| string | $blockname | - the basic name of a block (eg "navigation") |
| boolean | - is there one of these blocks in the current page? |
|
inherited |

| boolean | true if this region exists on this page. |
| my_syspage_block_manager::load_blocks | ( | $includeinvisible = null | ) |
Load blocks using the system context, rather than the user's context.
This is needed because the My Moodle pages set the page context to the user's context for access control, etc. But the blocks for the system pages are stored in the system context.
Reimplemented from block_manager.

protectedinherited |
Returns an array of region names as keys and nested arrays for values.
| array | an array where the array keys are the region names, and the array values are empty arrays. |

| bool | True if all of the blocks within that region are docked |
Return false as from MDL-64506
|
inherited |
Determine whether a region contains anything.
(Either any real blocks, or the add new block UI.)
(You may wonder why the $output parameter is required. Unfortunately, because of the way that blocks work, the only reliable way to find out if a block will be visible is to get the content for output, and to get the content, you need a renderer. Fortunately, this is not a performance problem, because we cache the output that is generated, and in almost every case where we call region_has_content, we are about to output the blocks anyway, so we are not doing wasted effort.)
| string | $region | a block region that exists on this page. |
| core_renderer | $output | a core_renderer. normally the global $OUTPUT. |
| boolean | Whether there is anything in this region. |
|

| $newweight | the new weight. |

Will be a subset of $allblocks, but with array keys block->name. Access this via the get_addable_blocks() method to ensure it is lazy-loaded.
|
protectedinherited |
Used by the block move id, to track whether a block is currently being moved.
When you click on the move icon of a block, first the page needs to reload with extra UI for choosing a new position for a particular block. In that situation this field holds the id of the block being moved.
